Abstract: 1.   Quadratic storage container.   2.1  It is known to cover the inlet openings of measuring vessels for analyzing blood, plasma or the like, with which a storage container of this type is furnished, with a foil in order to protect them against contamination. When removing the foil, however, dust lying on the foil can be pushed off,  said dust then falling into the measuring vessels and thus affecting the measurement results.  It is the object of the invention to design a storage container in such a way that the functionability of the measuring vessels is fully maintained in every case.   2.2  To accomplish this, it is provided that openings (4, 5) which serve to guide an ejector rack (2) and are provided on the upper side  (8)  of the storage container,  are arranged laterally outside of the covering area of the measuring vessels (6).   2.3  Since the measuring vessels are hereby fully covered by the upper side (8) of the storage container (1), the use of a foil having the aforementioned disadvantages is no longer necessary.   3.   Fig. 1.

Title: Adaptive Hybrid ARQ Coding Schemes for Slow Fading Channels in Mobile Radio Systems
Inventor: SAYEED ZULFIQUAR
IPC: H04L1/16
Filed: 1997-02-10
Abstract: A method and apparatus for performing adaptive hybrid automatic repeat request (ARQ) coding in which the coding is modified based on the acknowledgements returned by the receiver. In accordance with one illustrative embodiment of the present invention, the state of the channel is implicitly determined by the transmitter based upon the frequency of acknowledgments (ACKs and NACKs) arriving from the receiver. For example, since a NACK implies a weak received signal strength, the code rate of the FEC is advantageously reduced in response to such an acknowledgement. On the other hand, the code rate of the FEC is advantageously increased in response to an ACK. In accordance with another illustrative embodiment of the present invention, the acknowledgement returned by the receiver is modified to convey the number of errors in the corresponding received data packet. In particular, a Reed-Solomon (RS) outer code is employed in the FEC to enable the receiver to determine the number of errors in the received data packet. If the acknowledgement indicates a large number of errors at the receiver, the code rate of the FEC is advantageously reduced in response thereto.

Patent CA-2210616-A1 (CA)
Title: Soft-start switch with voltage regulation and current limiting
Inventor: PIEPER MARK S
IPC: G05F1/40
Filed: 1997-07-16
Abstract: A MOSFET, an op-amp, a comparator circuit, and voltage dividers with capacitors are employed in combination to effectuate a soft-start switch with current limiting. The transconductance of the MOSFET is employed so that no sense resistor is required. The MOSFET and op-amp are configured as a closed-loop feedback circuit in which the output of the op-amp is coupled to the gate of the MOSFET and the inverting input of the op-amp is coupled to the output of the soft-start switch via a voltage divider. A first RC circuit provides a voltage to the non-inverting input of the op-amp which can be triggered to gradually rise from a value close to zero to some reference voltage so as to soft-start a load. Current limiting means are effectuated by a comparator circuit and voltage dividers with capacitors. The current limiting means brings the MOSFET to an OFF state and the non-inverting input of the op-amp close to zero volts if the op-amp charges a second RC circuit so that the voltage drop across its capacitor exceeds a predetermined limit-reference, and also, once the current limiting means brings the MOSFET to the OFF state, the current limiting means allows the soft-start switch to begin a soft-start power-up after a pre-determined time dependent upon the time constant of the second RC circuit.

Title: Regeneration of active carbon and polymeric adsorbents
Inventor: ROGERS DEREK J
IPC: C02F1/467
Filed: 1997-11-20
Abstract: Method for the regeneration of active carbon and polymeric adsorbents having oxidizable, organic pollutants adsorbed thereon by electrochemical and chemical means and apparatus therefor. The method involves a desorption step and a decomposition step. Desorption is accomplished in one embodiment by flowing an aqueous stream at a preselected pH through the adsorbent material. Generally, decomposition is accomplished by contacting an aqueous stream containing an organic pollutant with hydroxyl radicals. Sequential or simultaneous desorption and decomposition can also take place during electrolysis in an electrolytic cell. During decomposition the active carbon canbe made a carbon bed electrode of the cell. Electrolysis to produce peroxide can take place in the presence of a transition metal or a chelate of a transition metal while feeding an oxygen containing gas to the electrolysis cell.

Title: One-part, low viscosity, moisture curable composition
Inventor: DEPOMPEI MICHAEL F
IPC: C08G18/48
Filed: 1997-01-13
Abstract: A one-part, low viscosity, moisture curable composition which exhibits excellent shelf stability in the absence of water, but which quickly cures at ambient conditions upon exposure to moisture in the air is a substantially anhydrous mixture containing an acetoacetate functional compound and a polyisocyanate functional compound. The composition can be suitably formulated for use as an ambient temperature, moisture curable adhesive, sealant or coating composition. The acetoacetate functional compounds have a relatively low viscosity as compared with conventional isocyanate functional compounds and thereby reduce or eliminate the need for plasticizers, organic solvents, or both. The cure chemistry of the composition simultaneously consumes and generates moisture at approximately the same rate thereby facilitating rapid cure under even low humidity conditions, and allows for efficient and facile curing of even thick layers of the composition.
